Bigger free_num for lv_obj_t? about lvgl HOT 7 CLOSED

I can modify the LV_OBJ_FREE_NUM define in lv_conf.h to set the the type of free_num. For example:

#define LV_OBJ_FREE_NUM uint16_t

Using 1000 element in a list could cause other issues. If an element is e.g. 50 px high, the last will be on 50000 px coordinate. Now the GUI should be between -16K and +16K. See misc/gfx/area.h

Interesting point. If I limit it to 300 then that would be enough (although still outside the 256 range for 8 bits). Either that or I'm more intelligent in how I load the list into memory and the listview.

If you tell what you would like to do hopefully I can suggest a solution. (in a new topic)

Thanks for the offer. Let me play about with it here and see what I can come up with first as I don't want to waste your valuable time (which should be devoted to further develping littlevgl!)

Okay, see what happens :)
Anyway, the updating of LV_OBJ_FREE_NUM still might be a useful thing.

from lvgl.

In lv_conf.h I added LV_OBJ_FREE_NUM_TYPE to define the type of the free number (e.g. uint16_t)

It is available in lvgl/beta. It is the beta version of v5.0 so there are non-backward compatible API changes in it.

Added in v5.0.0
